FI SYSTEM DIAGNOSIS 4-47
Step 2
1) Turn the ignition switch OFF.
2) Disconnect the TP sensor coupler.
3) Install the test harness to the TP sensor.
4) Check the continuity between terminal A and ground.
TP sensor continuity: ∞ Ω (Infinity)
(Terminal A – Ground)
5) If OK, then measure the TP sensor resistance at the test har-
ness terminals (between terminal A and terminal B).
6) Turn the throttle grip and measure the resistance.
TP sensor resistance
Throttle valve is closed: Approx. 1.1 kΩ
Throttle valve is opened: Approx. 4.3 kΩ
7) If OK, then measure the TP sensor resistance at the test har-
ness terminals (between terminal C and terminal D).
TP sensor resistance: Approx. 4.68 kΩ
(Terminal C – Terminal D)
09900-25008: Multi-circuit tester set
09900-28630: TPS test wire harness
Tester knob indication: Resistance (Ω)
Are the continuity and resistance OK?
8) After repairing the trouble, clear the DTC using SDS tool.
